Hyperlinks in Word documents can lead readers to a webpage, an external file, an email address, and a specific place of the document being read. They are commonly used in Word documents for their convenience. This article will teach you how to use Spire.Doc for Java to find and extract hyperlinks in Word documents, including hypertexts and links.

Find and Extract a Specified Hyperlink in a Word Document

The detailed steps are as follows:

• Create a Document instance and load a Word document from disk using Document.loadFromFile() method.
• Create an object of ArrayList<Field>.
• Iterate through the items in the sections to find all hyperlinks.
• Get the text of the first hyperlink using Field.get().getFieldText() method and get its link using Field.get().getValue() method.
• Save the text and the link of the first hyperlink to a TXT file using custom method writeStringToText().

Hyperlinks usually appear on texts. By clicking on a hyperlink, we can access a website, a document, an email address, or other elements. Some Word documents, especially those that are generated from web content, may contain irritating hyperlinks, such as advertisements. This article shows you how to programmatically remove one hyperlink or all hyperlinks in a Word document using Spire.Doc for Java.

Spire.Cloud.Office is a JavaScript document editor which you can use to create, edit, convert, print, view and save MS Word and Excel documents in a browser on Windows, Linux and Mac. This article demonstrates how to incorporate Spire.Cloud.Office online editor (JavaScript) into a HTML document, so you can run the editor directly in your web application or cloud application.

Step 1. Install Spire.Cloud.Office

Before you can embed the document editor in your HTML file, you’ll need to install Spire.Cloud.Office on your system.

• Install Spire.Cloud.Office for .NET on Windows
• Install Spire.Cloud.Office for Linux on Ubuntu

After installation, you can visit our sample file management system and editor on port 3000, and connect to our service via port 8000. In this tutorial, Spire.Cloud.Office is installed on our local server 192.168.0.111.

Step 2. Embed Editor in Your HTML Document

Below is a sample HTML in which our document editor is embedded. You can download it and modify some key parameters in it to run our editor in a HTML page.

Find Text and Add Hyperlinks for Them in PDF

With Spire PDF for Java, you can find all matched text in a specific PDF page and add hyperlinks to them. Here are the detailed steps to follow.

• Create a PdfDocument instance and load a sample PDF document using PdfDocument.loadFromFile()method.
• Get a specific page of the document using PdfDocument.getPages().get() method.
• Find all matched text in the page using PdfPageBase.findText(String searchPatternText, boolean isSearchWholeWord) method, and return a PdfTextFindCollection object.
• Create a PdfUriAnnotation instance based on the bounds of a specific find result.
• Set a URL address for the annotation using PdfUriAnnotation.set(String value) method and set its border and color as well.
• Add the URL annotation to the PDF annotation collection as a new annotation using PdfPageBase.getAnnotationWidget().add() method.
• Save the document using PdfDocument.saveToFile() method.

Sometimes after you have finished an Excel workbook, you may need to replace some of the existing pictures with better ones for the purpose of making the workbook more appealing and persuasive. In this tutorial, you will learn how to replace a picture in Excel using Spire.XLS for .NET.

Install Spire.XLS for .NET

To begin with, you need to add the DLL files included in the Spire.XLS for .NET package as references in your .NET project. The DLLs files can be either downloaded from this link or installed via NuGet.

PM> Install-Package Spire.XLS

Replace a Picture in Excel

The following are the detailed steps to replace a picture with another one using Spire.XLS for .NET.

• Create a Workbook object.
• Load a sample file using Workbook.LoadFromFile() method.
• Use Workbook.Worksheets[0] to get the first worksheet.
• Use Worksheet.Pictures[0] property to get the first picture from the first worksheet
• Use Image.FromFile() method to load an image from the specified file, and set it as a new value of ExcelPicture.Picture property. To do so, the original picture will be replaced with the new one.
• Save the document using Workbook.SaveToFile() method.

using Spire.Xls;
using Spire.Xls.Collections;
namespace ReplacePictureinExcel
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create a Workbook instance 
            Workbook workbook = new Workbook();
            //Load the Excel file
            workbook.LoadFromFile("input.xls");

            //Get the first sheet
            Worksheet sheet = workbook.Worksheets[0];

            //Get Excel picture collection
            PicturesCollection pictureCollection = sheet.Pictures;

            //Get the first picture from the collection 
            ExcelPicture excelPicture = pictureCollection[0];

            // Creates an Image from the specified file.
            excelPicture.Picture = System.Drawing.Image.FromFile("input.png");

            //Save the document
            workbook.SaveToFile("ReplaceImage.xlsx", ExcelVersion.Version2013);
        }
    }
}

Imports Spire.Xls

Data bars are a type of conditional formatting Microsoft Excel offers for visualizing the values in Excel cells. They can help you compare the values quickly because a cell with a longer bar represents a larger value, while a cell with a shorter bar represents a smaller value. This article will introduce how to add data bars in a range of cells using Spire.XLS for Java.

Install Spire.XLS for Java

First of all, you're required to add the Spire.Xls.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

<repositories>
    <repository>
        <id>com.e-iceblue</id>
        <name>e-iceblue</name>
        <url>https://repo.e-iceblue.com/nexus/content/groups/public/</url>
    </repository>
</repositories>
<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.xls</artifactId>
        <version>16.8.4</version>
    </dependency>
</dependencies>

Add Data Bars in Excel

The following are steps to add data bars in a range of Excel cells through conditional formatting:

• Create a Workbook instance.
• Load an Excel file using Workbook.loadFromFile() method.
• Get the worksheets collection using Workbook.getWorksheets() method, and then get the first worksheet using WorksheetsCollection.get() method.
• Get a specific cell range using Worksheet.getCellRange() method.
• Add a new conditional formatting to the cell range using ConditionalFormats. addCondition(), and then set the type of the new conditional formatting to DataBar using ConditionalFormatWrapper.setFormatType() method.
• Set the color of the data bar using DataBar.setBarColor() method.
• Save the document to another file using Workbook.saveToFile() method.

import com.spire.xls.*;
import com.spire.xls.core.IConditionalFormat;
import com.spire.xls.core.spreadsheet.collections.XlsConditionalFormats;

import java.awt.*;

public class applyDataBars {
    public static void main(String[] args) {
        //Create a Workbook instance
        Workbook workbook = new Workbook();

        //Load an Excel file
        workbook.loadFromFile("C:\\Users\\Administrator\\Desktop\\test.xlsx");

        //Get the first worksheet.
        Worksheet sheet = workbook.getWorksheets().get(0);

        //Add a conditional formatting and specify ranges
        XlsConditionalFormats conditional = sheet.getConditionalFormats().add();
        conditional.addRange(sheet.getCellRange("B2:B13"));

        //Add the conditional formatting of data bars
        IConditionalFormat format = conditional.addCondition();
        format.setFormatType( ConditionalFormatType.DataBar);

        //Set color for the data bars
        format.getDataBar().setBarColor( Color.GREEN);

        //Save to file
        workbook.saveToFile("ApplyDataBars.xlsx", ExcelVersion.Version2013);
    }
}

//Create a Presentation object
Presentation presentation = new Presentation();

//Load the sample PowerPoint file
presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\Spire.Presentation.pptx");

//Specify watermark text
String watermarkText = "E-iceblue";

//Get the size of the watermark text
Image image = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2d = (Graphics2D) image.getGraphics();
Font font = new Font("Arial", Font.BOLD, 20);
g2d.setFont(font);
FontMetrics fm = g2d.getFontMetrics();
Rectangle2D strSize = fm.getStringBounds(watermarkText, g2d);

//Initialize x and y coordinate
float x = 30;
float y = 80;

for (int rowNum = 0; rowNum < 4; rowNum++) {
    for (int colNum = 0; colNum < 5; colNum++) {

        //Add a rectangle shape
        Rectangle2D rect = new Rectangle2D.Float(x, y, (float) strSize.getWidth() + 10, (float) strSize.getHeight());
        IAutoShape shape = presentation.getSlides().get(0).getShapes().appendShape(ShapeType.RECTANGLE, rect);

        //Set the style of the shape
        shape.getFill().setFillType(FillFormatType.NONE);
        shape.getShapeStyle().getLineColor().setColor(new Color(1, 1, 1, 0));
        shape.setRotation(-45);
        shape.getLocking().setSelectionProtection(true);
        shape.getLine().setFillType(FillFormatType.NONE);

        //Add watermark text to the shape
        shape.getTextFrame().setText(watermarkText);
        PortionEx textRange = shape.getTextFrame().getTextRange();

        //Set the style of the text range
        textRange.getFill().setFillType(FillFormatType.SOLID);
        textRange.getFill().getSolidColor().setColor(Color.pink);
        textRange.setLatinFont(new TextFont(font.getName()));
        textRange.setFontMinSize(font.getSize());

        x += (100 + strSize.getWidth());

    }
    x = 30;
    y += (100 + strSize.getHeight());
}

//Save the document
presentation.saveToFile("output/Watermark.pptx", FileFormat.PPTX_2013);
